Vectaerovenator (meaning "Isle of Wight air-filled hunter"[1] due to the pneumaticity of the vertebrae) is a genus of tetanuran theropod from the Early Cretaceous period of what is now England (Lower Greensand Group; Ferruginous Sands).

[2] Comparative anatomical analysis shows that this taxon shares homoplastic features with megalosauroids, carcharodontosaurs, and some coelurosaurs, and cannot be reliably placed beyond Tetanurae incertae sedis, but has enough autapomorphies that it can be considered a valid genus.

It was determined to be a new species and was given the name Vectaerovenator inopinatus, meaning air-filled hunter, due to amount of air spaces found in the recovered vertebrae.

It was further determined that the material found belonged to one individual due to its general location, both in time and space, and the common similarity between the four vertebrae (this being the texture, and overall size).

When it was examined it was first thought to be a megaraptoran, but the authors did eventually recover it as a possible basal tyrannosauroid, although this also was done with some level of uncertainty, as it could easily belong under the superfamilies Allosauroidea or Megalosauroidea.
